Preparation of SnO2 Nanoparticles Doped With Palladium and Graphene and Application for Ethanol Detection

A novel ethanol gas sensor constructed with SnO 2 nanoparticles doped with palladium and graphene is described. By incorporating 0.1 wt% graphene and 3 wt% PdCl 2 into SnO 2 , the working temperature of the sensor can be reduced to 40 °C and the response is 4.6. The operation temperature can be decr...

Description
Summary:A novel ethanol gas sensor constructed with SnO 2 nanoparticles doped with palladium and graphene is described. By incorporating 0.1 wt% graphene and 3 wt% PdCl 2 into SnO 2 , the working temperature of the sensor can be reduced to 40 °C and the response is 4.6. The operation temperature can be decreased to near room temperature due to the increased oxygen adsorption by palladium and the high electron mobility by graphene.
